SELF-ACTING CANDLE-EXTINGUISHER.

Specification of LettersPatent.

Patented April 2a, 1908.

Application filed. June 7, 1907. Serial No. 377,810.

To all whom it may concern.

Be it known that I, ALEXANDER CRAWFORD FINDLAY, subject of the King ofGreat Brit: ain, residing at Perth, Western Australia,

and Commonwealth of Australia, have in-' vented certain new and usefulImprovements in Self-Acting Candle-Extinguishers, of which the followingis a specification.

The object of this invention is to automatically extinguish lightedcandles at any predetermined or given limit point of their lighting.

The instrument is principally designed for use by readers in bed so asto obviate any danger of fire by reason of the candle burning down afterthe reader has fallen asleep, and the appliance in its constructionprovides means whereby the candle upon being burned to its given limitthereby releases mechanism and so allows the cap to fall on to and extinuish the lighted candle.

l n order that the construction and use of my invention may be clearlyunderstood reference will now be made to the attached drawingsillustrating same and in said draw m s:-

. Figure 1 is a sectional elevation of the extin uisher as out of actionand attached to its 'ghted candle. Fig. 2 is'a similar view but showingthe appliance in action and the lighted candle extinguished. Fig. 3 is aplan view of Fig. 1.

In these drawings a is the candle on which the appliance is held bymeans of its frame, this frame is bifurcated and made with cir cularspring jaws a which embrace or grip the candle as shown, said framebeing also formed with the outer extensions between which the operativeparts are pivotally mounted as shown.

The extinguisher is set on the candle by the forked lever b atthedesired point as N, said fork being pivoted as at W. This fork acts in alet-go or releasing manner and at its end 0 suitably engages against thetoe c of the ush over leverd which is pivoted at al This ever isprovided with an urging spring as e which by its tail e impinges againstthe heel c of the lever d and said spring being held in osition by thepins 6 and c to the main frame as shown. To this lever d is pivoted thearm f as at f 1 and which latter carries the extinguisher cap f said armbeing formed with a snug piece whereby the arm sits on lever d as at fand so prevents the arm from falling backwards.

The operation of this self acting candle ex- I tinguisher is briefly asfollows :-The appliance beingplaced on the candle as in Fig. l is thenset at the point or limit as b to which it is desired that the candleshould burn, this is effected by pressing home the prongs of the let-gofork b and slightly embedding them in the candle so causing the pushover lever to be held in the locked position as seen in Fig. 1. As soonas the candle has burned down to its limit point 12 the fork b isthereby released so allowing the spring 6 to act and urge over the lever61 which by so doing pushes as f 4 against snug piece f and pushes thearm f over its perpendicular and thereby allows the cap f to fall overby gravity on to and extinguish the candle in the manner and position asshown in Fig. 2.

The candle may be extinguished by the cap f 2 prior to the limit point 6being reached or burned down to and as shown in dotted lines in Fig. 1and without disturbing the setting of the appliance which remains in itsset or locked position as shown in said figure.

What I claim as my invention and desire to secure by Letters Patent is:-

1. In an automatic candle extinguisher, the combination with a frameadapted to be applied to a candle, of a lever pivoted on the frame, anarm pivotally attached to the said lever provided with an extinguishingcap and having a lug thereon arranged to cooperate with the lever tonormally poise the cap in inoperative position, a spring normally actingto tilt the said lever and thereby dislodge the cap and permit movementthereof toward extinguishing position, and a device released by theburning of the candle for controlling the operation of the lever.

2. A self-acting candle extinguisher comprising a frame, a fork movablymounted on the frame, adapted to engage the candle and to be releasedthereby when the candle is consumed to a certain line, a spring-operatedlever movably mounted on the frame and held against operation by saidfork when the latter is held by the candle, and an arm provided with anextinguishing cap, said arm be ing operable by said lever when the sameis released by said fork, to carry said cap into position forextinguishing the candle.

3. In an automatic candle extinguisher, the combination with a suitableframe adapted for application to a candle or the like, of a leverpivotally mounted on the frame and having an eccentrically arrangedpivot thereon, an arm having its lower end cooperating with theeccentriovpivot of the lever having an extinguishing cap on the upperfree end thereof and provided with a lug to cooperate with the lever topoise the cap in inoperative position, and a spring controlled by theburning of the candle for operating the lever to unbalance theextinguishing cap and cause movement thereof towardextinguishingposition.

4. In an automatic candle extinguisher, the combination with a frameadapted to be applied to a candle, of a lever pivoted. on the frameprovided with an eccentrically arranged pivot and having a heel at oneside of its pivot adjacent to the said pivot, an arm having its lowerend cooperating with the eccentric pivot of said lever and provided withan extinguishing cap on its free end, means for poising the cap ininoperative position while the lever occupies a predetermined position,a spring cooperating with the heel portion of the lever and acting tooperate the latter to release the cap, and a second lever intermediatelypivoted on the frame, one end thereof cooperating with the lever firstmentioned and. the opposite end thereof cooperating with the candle forcontrolling operation of the extinguishing cap.

In testimony whereof I have hereunto set -my hand in presence of twosubscribing witnesses.

ALEXANDER CRAWFORD FINDLAY.
